Granted: 1898-10-01
Abstract: 5943. Cowper-Coles, S. O. March 10. Zinc; copper ; gold; lead ; silver.-Complex zinc ores, such as Broken Hill ore, are crushed and then mixed with 25 to 50 per cent. of zinc blende, tin ore or tailings thereof, or copper ore, and afterwards dead roasted. They are then washed, and afterwards screened, the fine dusty portion going to one series of leaching-vats, and the coarse particles to another. Each series of vats is treated similarly but separately with weak sulphuric acid, and the solution obtained is passed through a bed of zinc and carbon or iron and carbon, or both, whereby the copper is deposited. The ore remaining is then washed with water, and the lead extracted as plumbate by treatment with caustic soda, and deposited by electrolysis, after which the gold and silver are separated by means of potassium cyanide. The wash liquor from above is led to an evaporating-pan, and the zinc-sulphate solution obtained treated in a way to obtain zinc white. The above leaching operation is facilitated hy passing a current of electricity through the solution during the process, using an insoluble anode beneath the ore, and a zinc cathode, surrounded by a porous protector above the ore.
